The invention discloses a splicing and fusion method for numerical simulation calculation results of flow field partitions of a wind power plant, which is used for solving the problem of splicing and fusion of sub-model flow field simulation results after segmentation calculation of a large terrain during CFD (computational fluid dynamics) simulation calculation of a flow field of a large-scale wind power plant. The method comprises the following steps of: firstly, performing interpolation calculation on grid points in an overlapping region by utilizing a calculation result of the overlapping region of adjacent sub-models, then searching an incidence relation for calculation values of different sub-models through a statistical method based on the same grid coordinate points, determining a linear relation by utilizing a least square method, and then, correcting sub-model grid point values needing to be spliced and fused by utilizing a linear relation, and finally, merging corrected sub-model results to form a
